桩基是工程结构常用的基础形式之一,属于地下隐蔽工程,施工技术比较复杂,工艺流程相互衔接紧密,施工时稍有不慎极易出现断桩等多种形态复杂的质量缺陷,影响桩身的完整性和桩的承载能力,从而直接影响上部结构的安全。因此,其质量检测成为桩基工程质量控制的重要手段。 The pile foundation is one of the basic forms commonly used in engineering structures. It belongs to underground concealed works. The construction techniques are complicated and the technological processes are closely linked with each other. During construction, there are many defects such as broken stakes and other complicated forms of quality defects, Body integrity and pile carrying capacity, which directly affects the safety of the superstructure. Therefore, the quality inspection of pile foundation engineering quality control has become an important means.
